18 Servings
Ingredients
- 1 cup 2 sticks salted butter, melted and cooled slightly
- 1 cup light brown sugar packed
- 1 cup granulated sugar
- 1 large egg
- 2 large egg yolks
- 1 tablespoon vanilla extract
- 2½ cups all-purpose flour
- 1 tablespoon cornstarch
- 1 teaspoon baking powder
- 1 cup butterscotch chips divided
Instructions
Preheat and Prepare the Baking Pan
- Preheat the oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper, leaving an overhang on two sides to facilitate removal of the bars after baking.
Combine the Wet Ingredients
- In a large mixing bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth and well incorporated. Add the whole egg and egg yolks one at a time, whisking after each addition until fully blended. Stir in the vanilla extract.
Add the Dry Ingredients
- In a separate bowl, whisk together the flour, cornstarch, and baking powder. Gradually add the dry ingredients to the wet mixture, stirring until mostly combined. Avoid overmixing at this stage.
Incorporate the Butterscotch Chips
- Fold ¾ cup of the butterscotch chips into the batter, ensuring they are evenly distributed. The batter will be thick.
Transfer to the Pan and Bake
- Spread the batter evenly into the prepared pan. Sprinkle the remaining ¼ cup of butterscotch chips over the surface. Bake for 25 to 30 minutes, or until the top is golden brown and a toothpick inserted in the center comes out with moist crumbs but no raw batter.
Cool and Serve
- Allow the bars to cool completely in the pan. Once cooled, use the parchment overhang to lift the bars out of the pan. Slice into squares and serve.
Notes
To make these Butterscotch Bars gluten-free, substitute the all-purpose flour with a high-quality 1:1 gluten-free baking flour blend that includes xanthan gum. Additionally, verify that your baking powder and butterscotch chips are certified gluten-free, as some brands may contain trace amounts of gluten.
